This wiki is mainly used by developers for organization of e.g. SageDays and discussion of long-term projects. Since it ''is'' a wiki, pages should be made to last over many, and frequent, changes. If an external link is made, please attach relevant files/content to avoid broken links.

== New-style SPKGs ==

There is a single authoritative place to learn about the
specific set of packages (new-style SPKGs) that Sage uses: The
[[https://github.com/sagemath/sage/tree/develop/build/pkgs|SAGE_ROOT/build/pkgs/]] directory
in the Sage distribution. Each SPKG is represented by a subdirectory. The structure
of these subdirectories is explained in
the [[https://doc.sagemath.org/html/en/developer/packaging.html|Developer's Guide|]].

Since Sage 9.2, the [[https://doc.sagemath.org/html/en/reference/spkg/|spkg section of the Sage reference manual]] is automatically generated from the information in `SAGE_ROOT/build/pkgs/`. ([[https://trac.sagemath.org/ticket/29655|Trac #29655]] improves the formatting of this information.)

Use the following shell commands below to access the information from the `SAGE_ROOT/build/pkgs`
directory of your copy of Sage:

 * Standard packages: `./sage -standard`
 * Installed packages: `./sage -installed`
 * Optional packages available: `./sage -optional`
 * Experimental packages available: `./sage -experimental`
 * Details about an SPKG: `./sage -info <SPKG>`

For some advanced package tools, use `./sage -package`

= About this wiki =

'''Editing the wiki.''' Page editing uses the MoinMoin syntax. To edit the wiki, you will need a log in using your [[https://trac.sagemath.org/#legacy-account-request|legacy sage-trac account]] account; a !GitHub account cannot be used for this. If you edit an existing page with a long history, a key question is: "If someone opens this page tomorrow, will they be able to tell which information is current and which is outdated?" Edit accordingly.

'''SageWiki maintenance.''' The [[SageWikiMaintenance page]] attempts to reorganize the wiki, which has accumulated many outdated pages.
